Practical Network-Based Techniques for Mobile Positioning in UMTS

This paper presents results of research on network-based positioning for UMTS (universal mobile telecommunication system). Two new applicable network-based cellular location methods are proposed and assessed by field measurements and simulations. The obtained results indicate that estimation of the position at a sufficient accuracy for most of the location-based services does not have to involv...

Usage of mobile location techniques for UMTS network planning in urban environment

The paper addresses the use UMTS terminals for “probing” the signal level as a function of location for the purposes of network planning and monitoring. Potential UMTS location techniques are presented and the location performance of time delay and correlation based techniques is estimated by using impulse responses calculated by three-dimensional simulation techniques. The probing accuracy is ...
